A SysOps administrator needs to monitor Amazon S3 for object-level operations such as PUT and DELETE events in a specific bucket. The administrator wants these events to be sent to an Amazon SQS queue for downstream processing by an application. Which solution should be used to achieve this with the least operational overhead?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Use Amazon CloudWatch Events to match S3 API calls from CloudTrail and route to an SQS queue.
This adds latency and complexity. CloudTrail delivers logs within ~15 minutes, not real-time. S3 event notifications are more direct and timely.
B
Best answer
Configure an S3 event notification on the bucket to send events to an SQS queue.
This is the simplest and most efficient method. S3 can publish object-level events directly to SQS with minimal delay.
C
Distractor review
Deploy an application that periodically polls S3 for changes using ListObjects.
Polling is inefficient, not real-time, and introduces significant overhead compared to event-driven notifications.
D
Distractor review
Use AWS CloudTrail to deliver logs to CloudWatch Logs, then create a metric filter and trigger a Lambda function to send to SQS.
This is overly complex and introduces delays from CloudTrail log delivery and processing.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

Question 1
A company uses Amazon CloudFront to deliver content to a global audience. The origin is an Application Load Balancer in us-east-1. The SysOps administrator wants to reduce costs by minimizing the number of requests that reach the origin server. Which action should the administrator take?
Question 2
A company runs a batch processing application on Amazon EC2 that runs for 2 hours every night. The workload can tolerate interruptions. Which EC2 purchasing option provides the lowest cost for this use case?
Question 3
A SysOps administrator needs to monitor the CPU utilization of an Amazon RDS DB instance and receive an alarm when CPU utilization exceeds 80% for 5 consecutive minutes. Which AWS service should be used to create this alarm?
Question 4
A company runs a critical web application on Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). The application uses session stickiness (sticky sessions) to maintain user sessions. The SysOps administrator notices that when instances are replaced during a scale-in or failure event, users lose their session data. The administrator needs to preserve session data across instance failures without losing stickiness benefits. What should the administrator do?
Question 5
A company runs a production web application on a single Amazon EC2 instance. The application experiences a predictable and steady workload 24/7. The SysOps administrator wants to minimize compute costs for this instance while ensuring it remains available during the expected workload. Which EC2 purchasing option should the administrator use?
Question 6
A company has a VPC with public and private subnets. The private subnets host application servers that need to make outbound HTTPS connections to the internet. The SysOps administrator must implement a solution that provides outbound internet connectivity while preventing inbound connections from the internet. Additionally, the solution must allow the company to control which domains the application servers can access. Which solution should the administrator implement?
FAQ
Questions learners often ask
What does this SOA-C02 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Configure an S3 event notification on the bucket to send events to an SQS queue. — Amazon S3 can directly send event notifications to Amazon SQS, Amazon SNS, or AWS Lambda when specific events occur in a bucket. By configuring the S3 bucket to send events to an SQS queue, the administrator can avoid additional components like CloudWatch Events or Lambda. CloudTrail can also capture S3 API calls but requires additional setup and is more suited for auditing rather than real-time event-driven processing. EventBridge can consume events from AWS services but would add unnecessary complexity.
